You can put this solution on YOUR website!
this equation is in \"vertex\" form __ y=a(x-h)^2+k __ where (h,k) is the vertex
\n" ); document.write( "__ the axis (of symmetry) passes through the vertex and has the equation x=h\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "vertex __ (-4,0)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "axis __ x=-4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x can be any value so the domain is all real numbers\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "because of the square function, y can't be less than 0; so the range is all real numbers >= 0 \n" ); document.write( "
\n" );
